"Absolute WORST experience I’ve ever had with a company! They are extremely predatory and convinced my 63 year old mother that she had to sign the contract THAT DAY, and she didn’t even understand what she was signing! The first day they were scheduled to do the job, they showed up hours late, and said they “weren’t the right crew to do the job”. We then had to wait a couple weeks for a different crew to come, and when they came they said they weren’t the right crew to do the job either!! 2 weeks later, ANOTHER crew came and said THE SAME EXACT THING!!! So after 3 times of getting the runaround, I was completely FED UP with this horrible company and decided to cancel the contract. They FINALLY did let me cancel, but are demanding we still pay $600! After all they put us through over 3+ months, they had the nerve to charge us $600 for an outlet! PLEASE AVOID THEM AT ALL COSTS! All they care about is dollar signs, not about the QUALITY of their work or customer service."

Matthews offers a variety of products and services to permanently correct basement and foundation problems. Award wining. Additional DBA - MWA Acquisition LLC .

"The salesperson David was very honest and had no interest in upselling. He strongly advised against any interior drains for my basement, and he instead recommended an exterior drain called HydroBlox for my backyard. The estimate for the HydroBlox was $3,400. The installation occurred a few weeks later. Three employees used a machine to dig a trench in my backyard, and then because of utility lines, they hand-dug another trench in my side yard. They installed the pieces of HydroBlox and covered them with dirt. I expect the HydroBlox to properly drain the water from my yard, but if they do not, then I will update my review in the future."

"This one-star rating is generous! We are seven weeks into a four-day job at our house! The have been back three times to finish the job and it is still not done. My back yard is a mud pit! I have been informed by the "office" that it will take two more weeks before I can be put on the schedule for a crew to come back. The crew is working from their Lancaster office, and the managers won't return phone calls and are hiding behind the receptionist. I work just a few miles from their Lexington office, so I decided to pop in and talk to a different person only to find out that there is no staff in this office. The website for the Lexington office has a picture of the building and posted hours of 9 am to 6 pm, but it is just a building with mailboxes and a few shared meeting rooms used by several companies. Customer service is absolutely horrible. Think twice before hiring USS!"

Basement Waterproofing questions, answered by experts

Physically, the most challenging part of finishing a basement is installing egress windows or doors when the space is below ground level. Mentally, the hardest part may be envisioning the project and planning around load-bearing and mechanical obstacles.

Egress windows or doors are required in finished basements to meet safety and building codes. If your basement is unfinished and used as a storage space, egress windows are not required, but anything considered a habitable space must have an additional point of egress in addition to the stairs.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

Yes, water and water vapor can seep through cracks in your basement floor, which means you should address all basement floor cracks, even if they don’t indicate structural issues. Sealing settling cracks and shrinkage cracks is a good idea to keep water and moisture outside where it belongs. Doing so can improve your indoor air quality, reduce the risk of mold growth, make your home more comfortable, and help prevent pest infestation.

Permits may be required for major repairs, structural work, or electrical and plumbing restoration after a flood. Check with your local building department to determine permit requirements and associated fees for your flooded basement cleanup project. Obtaining the correct permits helps ensure work is done safely and up to code.
